wuvvum Posted March 7, 2020 Share Posted March 7, 2020 This is probably going to be a slow burner as the old crate needs a fair bit of work and I have other fleet members to keep on top of, but I'll update it as and when. This is the Merc earlier this afternoon: I have been attempting to remove the starter motor, which has packed up leaving the car immobile on my drive. The top bolt came out easily enough, but the lower bolt had to be got to from underneath the car, hence it being up in the air. A gravel driveway is not the ideal environment for jacking a car up - a scissor jack is all but useless and axle stands even more so, hence the combination of trolley jack and wheels under the sill. Both bolts and the wiring harness removed, it quickly became apparent that (unless I'm missing something) the starter motor ain't going to come out without the engine mount being removed. Even then it looks like it's going to be tight to get it past the studs. So tomorrow (or when next get time / can next be arsed) I've got to try and jack the engine up without breaking anything so I can remove the engine mount and see if I can then wiggle the starter out. If it still won't come out then I'm a bit stuck, unless I can wind the studs out of the block, but I'm not holding my breath that that'll work. Also I bought a bottle of touch-up paint off eBay. As I mentioned previously, the car was originally beige and has been resprayed metallic green at some point in its life - I had assumed the colour was Mercedes Silbergrün. The paint arrived a few days ago and I tried it out on a small patch of peeled paint on the bonnet. Yeah, that ain't Silbergrün is it. Not even close. So I now have a car that needs paintwork, and no idea what colour it is. Epic. HMC, stripped fred, Uncle Jimmy and 26 others 29 Link to comment Share on other sites More sharing options...
Peter C Posted March 7, 2020 Share Posted March 7, 2020 Bookmarked! That’s a cracking looking motor. Cavcraft 1 Link to comment Share on other sites More sharing options...
spartacus Posted March 7, 2020 Share Posted March 7, 2020 That looks great, even on tyres on the drive! I'm sure you know but if you can take a sample of the paint, (filler flap), to your local paint suppliers they should be able to match it. I'm certain you're going to tell me you know that, and there's no filler flap, and that the next smallest panel is the boot lid...

Skizzer Posted March 7, 2020 Share Posted March 7, 2020 Excellent. This looks a lot like the birth of another AS legend. Needing to remove an engine mount to extract the starter motor doesn’t sound fun though. If a jack is difficult on a gravel drive, then an engine crane is going to be a laugh and a half.

The filler flap locks on the central locking. The central locking works on a vacuum provided by the engine. The engine cannot currently provide a vacuum as it can't be turned over due to the starter motor being knackered. The next smallest panel is the boot lid.

I'm wondering whether I'm being thick and there's actually a really easy way to get it out - unfortunately there doesn't appear to be a Haynes manual (or equivalent) available for the W114/5.

xtriple Posted March 7, 2020 Share Posted March 7, 2020 If you can find the feed pipe for the vaccum to the flap/bootlid, a gentle(ish) suck will release the central locking. I had a 116 that had the same system and lost all vaccumn and so couldn't get into various bits. On mine it was under the bonnet on the r/h/s bulkhead. Any piece of trim taken to a paint supplier can be matched which is how I found out that Bentley Brooklands green was the same as Morgan Connaught green. You could get the Morgan paint but not the Bentley... purplebargeken and wuvvum 2 Link to comment Share on other sites More sharing options...
wuvvum Posted March 8, 2020 Author Share Posted March 8, 2020 Very little progress on the Merc today. I went out and had another fiddle with the starter motor to see if there was a way of getting it out that I'd missed yesterday, but no dice. I got the engine mount nuts / bolt cracked off - four of the five were fine but one was a right twat to get to, almost impossible with the starter motor in the way but managed it eventually with a combination of UJs and extension bars, plus much swearing. I didn't actually take the mount off though - I'm loath to do so until I'm certain that needs to happen as I really don't like the idea of jacking the engine up on the sump - it's a heavy bastard and I have no idea how strong the sump is. Obviously I'll use a bit of wood to try and spread the load, but the sump isn't flat so there's a limit to how much spreading will be possible. I found a seller in Australia offering a CD-ROM manual for the W115 220D, so I've ordered one. I've had a couple of CD manuals in the past and they have been very variable in quality - I'm hoping this one will be of at least some use. I did notice when trying to manoeuvre the starter out that there are quite a lot of metal particles on the bit which goes inside the bellhousing, which is not unexpected but still not a great sign. I'm hoping that it's the starter pinion which has lost its teeth - if it's the flywheel ring gear then I'm looking at a whole nother level of shit and I will be asking a mod to migrate this thread across to the For Sale forum.

wuvvum Posted March 14, 2020 Author Share Posted March 14, 2020 The workshop manual arrived yesterday, from Australia. Pretty impressive really. Unfortunately the section about removing the starter motor bears no resemblance to the setup on my car - I assume it's the petrol engine setup - so I'm no further forward.

axelvic Posted March 14, 2020 Share Posted March 14, 2020 I had a 220 diesel Manny years ago, and I’m quite sure I replaced the starter without removing the engine mount. Unfortunately I can’t remember how. I found a “Chiltons” guide and it doesn’t mention the engine mount having to be removed.

garbaldy Posted March 14, 2020 Share Posted March 14, 2020 Have you actually tried to unbolt the starter from the belhousing yet ? There could well be enough movement to lift up or down above the mount, I can't remember what car I've had this on but did manage with a good but wriggling.

Yep, that photo at the top of the page is the same one as in the CD manual I've bought. My setup looks nothing like that. For one thing there's no mounting bracket on the end of the starter - it's held on solely by the two bolts through the bellhousing. 3 minutes ago, garbaldy said: Have you actually tried to unbolt the starter from the belhousing yet ?

Yep, starter is unbolted from the bellhousing, cables removed etc. There's nothing physically holding it onto the car. The problem is that it hits the engine mounting whilst the bendix is still well inside the bellhousing, which means you can only wiggle the starter by a few degrees each way before it catches, and that's not enough to clear any of the engine bay paraphernalia.

I shall have a look at that as a possibility, but I have to say it did look like the engine mount was going to be the main issue. I have to say I didn't find getting the mounting bolts out all that difficult - yes they were a bit awkward but not the worst I've ever encountered. Maybe the setup on the W123 is different.

Thats a bummer so definatly mount off job, have you got any old rubber that could be used between jack and sump, stops sliding and is more forgiving on the metal than wood.

wuvvum Posted March 14, 2020 Author Share Posted March 14, 2020 It's out. No idea why I couldn't see this last week, but if you do exactly the right sequence of twists and wiggles at exactly the right time it will just clear the engine mount. Getting it out of the engine bay involved more wiggling and unbolting the inlet pipe for the heater matrix but still less traumatic than removing engine mounts or steering idler arms. Teeth on the pinion don't look in the first flush of youth. KruJoe, Stanky, RobT and 10 others 13 Link to comment Share on other sites More sharing options...

It's economically viable to repair for someone with the right facilities. Engine needs to come out, then the flywheel can be unbolted and either a complete replacement flywheel fitted or a new ring gear fitted to the existing flywheel. There's a complete second hand but OK looking flywheel on eBay for 133 quid, so not cheap but not ruinously expensive either. I can't take the engine out on my drive though, and I can't afford to pay a garage to do it for me. Cavcraft and stonedagain 2 Link to comment Share on other sites More sharing options...
